Re: [Bacula-users] Backing up more than 200 servers

John,

The Fulls of the weekend are canceled because during the week I have more than 200 servers (with small volume data) running full backups. When the incremental backups of these servers starts during the weekend my bacula-sd stop to responding (I'm using bconsole to check this) and my full jobs of the weekend stop to work. I believe it is because of the value "Max Concurrent Jobs" in bacula-dir equals "60".

My question is:

How do full backups during the week (starting on Tuesday, Wednesday and Thursday) and the incremental backups on Saturday and Sunday without generating problems on fulls backups that run during the weekend?

I think adjusting the values of "Max Concurrent Jobs" in bacula-dir and bacula-fd to 200. In my bacula-sd I set this value to 10. This solves the problem?

I have bacula-client installed on 200 servers

Thanks,

Rodrigo

Yes of course. Other bacula users on the list do that. I have heard
reports of 1000 machines being backed up by bacula.

How does full get canceled? I am confused.

I did not look at the Phil Stracchino. Don't you have bacula installed
on all 200 machines?

You should really upgrade to 5.0.1 if possible.
